Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single tank is used for catalytic ozonation evaluation, then the device structure is simple, but the aeration mode and position cannot be adjusted and sampling is limited to inlet and outlet only
Solution Approach 1:
The oxidation pond is divided into two independent tank bodies (A and B) with different functions. Tank A is dedicated for aeration with multiple sampling points, while Tank B is for overflow and outlet. This segmentation allows independent optimization of each tank's features without compromising the other, enabling adjustable aeration modes and positions while maintaining structural clarity.
Solution Approach 2:
Multiple sampling holes are opened at different positions (front, side, back walls) and heights of Tank A, transforming the sampling capability from a single point (inlet/outlet only) to multiple spatial points. This dimensional expansion enables comprehensive observation of gas-liquid-solid phases throughout the tank volume.
2Measurement precision
If sampling holes are opened at multiple positions, then comprehensive observation is achieved, but the tank structure becomes more complex
Solution Approach 1:
The tank bodies are equipped with multiple types of detachable components including sampling needles, ozone aeration pipes, water inlet pipes, and overflow sieve plates. These universal components can be installed, removed, and repositioned according to different experimental requirements, providing multi-functionality without permanently complicating the tank structure.
Solution Approach 2:
Sampling needles and ozone aeration pipes are designed as detachable components that can be easily installed and removed. This allows for simple replacement and reconfiguration without requiring complex permanent installations, reducing the overall structural complexity while maintaining comprehensive sampling and aeration capabilities.
3Adaptability or versatility
If square tank bodies are used, then the design matches actual production processes, but the device deviates from conventional round tank designs
Solution Approach 1:
The tank bodies are designed with a square cross-section rather than the conventional round shape. This parameter change in geometry better simulates actual production oxidation ponds, improving the adaptability and versatility of the evaluation device for predicting full-scale plant performance, while the modular construction approach keeps fabrication manageable.
4Adaptability or versatility
If ozone aeration pipes are detachable, then aeration parameters can be adjusted, but the connection structure becomes more complex
Solution Approach 1:
The ozone aeration pipes are designed as detachable components that can be freely installed at different positions and heights within Tank A, and can be removed for reconfiguration. This dynamic design allows flexible adjustment of aeration parameters (position, height, configuration) without requiring permanent fixed installations, enabling adaptation to different experimental conditions while keeping the connection structure relatively simple through standardized interfaces.

Function Achieved in This Case
Enables comprehensive observation and evaluation of gas, liquid, and solid phases, allowing for more accurate experimental data that can be easily scaled to actual production processes, and facilitates the adjustment of ozone aeration parameters for improved catalytic ozonation efficiency.
Implementation Method 1
Catalytic ozonation, as an effective method for removing organic matter from wastewater, is widely used in wastewater treatment. In the process of sewage treatment, catalytic ozonation is a three-phase reaction of gas-liquid-solid (ozone, sewage and catalyst)
Implementation Method 2
each of the tank body A and the tank body B is provided with a filler supported overflow sieve plate

AI summary
The invention discloses a double-tank oxidation pond for evaluating catalytic ozonation efficiency, comprising detachable tank bodies made of organic glass, movable ozone aeration pipes and sampling holes. Each tank body has three sections. The height of ozone aeration tube and the number of the holes can be adjusted. The holes are distributed at different positions of the tank bodies for real-time in-situ sampling. It is easy to observe the distribution profile of the gas, liquid and solid phases in the tank bodies. The square double-tank structure is similar to actual production process, and thus the experimental data is easy for computer simulation to enlarge to the actual production process. The size of the ozone aeration pipe and the position of holes in the tank can be adjusted to evaluate the catalytic ozonation effect of sewage treated by different aeration ways and aeration heights.
